中電(dian)氣設備選擇不當(dang)造(zao)成的(de)常(chang)見(jian)錯誤：生產過程中交流(liu)接(jie)觸器的(de)體(ti)(ti)積選擇不當(dang)，不同(tong)組的(de)插座控制電(dian)路安裝了相同(tong)體(ti)(ti)積的(de)交流(liu)接(jie)觸器，三相負載的(de)差異不完全考慮過的(de)。在(zai)平衡(heng)狀態下，不能在(zai)所有正(zheng)常(chang)模型中選擇某些組的(de)輸出交流(liu)接(jie)觸器的(de)電(dian)流(liu)水平。基本上，電(dian)流(liu)水平是通過一(yi)個步驟(zou)選擇的(de)，該(gai)步驟(zou)會(hui)導(dao)致交流(liu)接(jie)觸器在(zai)高溫天氣下運(yun)行期間燒(shao)斷(duan)。

根據(ju)電(dian)(dian)氣設(she)備(bei)的(de)接(jie)線規定，接(jie)線盒可(ke)安(an)裝在封閉(bi)或半封閉(bi)的(de)金屬(shu)外殼中或屏幕上，以(yi)(yi)形成配電(dian)(dian)室設(she)備(bei)。如果一切正(zheng)常(chang)，可(ke)以(yi)(yi)使用(yong)(yong)手或控制開關連接(jie)或斷(duan)開電(dian)(dian)源電(dian)(dian)路。常(chang)見的(de)錯誤(wu)或異常(chang)取決于(yu)家(jia)用(yong)(yong)電(dian)(dian)器的(de)維護，以(yi)(yi)斷(duan)開電(dian)(dian)路或警報(bao)。識(shi)別(bie)儀可(ke)以(yi)(yi)在信息模式下顯示各種主(zhu)要參(can)數(shu)，還可(ke)以(yi)(yi)調(diao)整(zheng)某些電(dian)(dian)氣設(she)備(bei)的(de)主(zhu)要參(can)數(shu)，并(bing)提醒或發出所有正(zheng)常(chang)工作設(she)置的(de)偏差(cha)信號。常(chang)用(yong)(yong)于(yu)發電(dian)(dian)，配電(dian)(dian)和變電(dian)(dian)站。
